Surveys serve as a great tool for gathering information from a sample of people and can take multiple forms but are most common in the form of a questionnaire, either written, online or over the phone.

In this tutorial, I’m going to walk us through how to build an automated Phone Survey System which is a form of an Interactive voice response (IVR) system. An IVR system is a technology that allows a computer to interact with humans through the use of voice and DTMF tone input via the phone’s keypad. To build this application, I will be working with the Twilio Python Helper Library, the Flask framework for Python and Google Sheets. Below is a high-level overview of how the application works:

For the purpose of building this application, I have selected the following three questions to include in the survey:

  1. Do you own or rent a house?
  2. What is your marital status?
  3. How old are you?

Note that even though we have kept the survey questions to three, the approach that we will be adopting to build the application scales seamlessly to as many questions as we want and also to other question types.
